LEAP Bridge V8i

New Features in CONSPAN v.8.0.0

• Create designs according to CALTRANS Amendments v3.06.01.
  
  
• Specific enhancements include:
  
  
  • Maximum debonding limit is set to 50% per row and 33% total.
    
  • Double Tandem Vehicle is automatically selected for continuous span analysis.
    
  • Fatigue I Limit State (with 1.75 LL factor) is provided  for compression check of concrete stress.
    
  • Fatigue truck added to library and automatically selected for Fatigue I Limit State.
    
  • CALTRANS permit vehicles P5 through P15 is automatically selected for analysis under Strength II Limit State.
    
  • There is reduced impact for permit trucks (Strength II) of 0.25 rather than 0.33.
    
  • CALTRANS specific beam cross sections added to library (I-beams, U-beams, Rect beams with circular voids).
    
  • Effective flange width is provided as per CALTRANS criteria, similar to LRFD 2008 changes.
    
  • New tension check/limit is provided under Service III for PS+DL combination.
    
    
• CONSPAN is now updated to include the 2008 AASHTO LRFD interims. Primary changes are the introduction of new equations for computing Beta/Theta (the older method of interpolating from tables is retained as an option), simplified computation of effective width of flange, and some minor changes to anchorage zone reinforcement.
  
  
• A new Strand Pattern Input Wizard now allows definition of straight/draped strands in an easy to use, point and click graphical user interface. It also generates production quality printouts that display strand patterns graphically.
  
  
• 2D views feature improved labeling/dimensioning.
  
  
• Export to DXF now writes the stirrup information in addition to overall geometry and prestressing strands.
  
  
• Stirrup information is also exchanged with AASHTOWare's Virtis/Opis database.
